Whats the longest wait you've had for a transfer to go through. I used shapeshift late last night and it still hasn't come through. I just did another one and it went right through.
I did not experience a very long waiting for confirmation in terms of transferring altcoins. I think when the SegWit2x was implemented early August when I think it was poloniex that implemented 40 confirmations before the transfer will finally take place, I waiter for several hours but it was not overnight.
